In an electric motor having a permanent-magnet rotor (16), the shaft (18) is mounted under axial spring pressure in bearings (14) of a casing (10), thrust rings being disposed between the bearings (14) and the rotor (16). At least one thrust ring is formed as a ferromagnetic spring washer (24) whose radially inner hub region (28) is axially up against the bearing (14) and whose radially outer circumferential region (30) is axially up against the rotor (16), the hub region (28) and the circumferential region (30) being joined resiliently to one another. |
